Application filed January 22, was. ee-i1 No. 614,083."

To all whom it may concern:

Be it known that I, DORRELL D. BRIGGS, a citizen of the United States, residing at Les Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Concrete" Building Blocks, of which the following is a specification.

My'invention relates to improvements in concrete building blocks and specifically to the hollow type block, the primary object thereofbeing the provision .of such a member that may be effectively used in conjunc tion with connecting tiles or slabs for forming a rigid hollow wall for all forms of buildings.

A further object of the invention is the provision of such a building block that is comparatively simple of construction, the

, same being manufactured preferably by molding the walls being formed by using these blocks in conjunction with connecting tiles or slabs in a simple and highly efficient manner.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a fragmentary cross sectional view through one portion of a wall formed by my blocks, showing fully the manner of employing these blocks in conjunction with the connecting tiles or slabs.

Figure 2 is a perspective view of the block per se.

Figure 3 is a view similar to Figure 1, disclosing one of the corner blocks having connection with the blocks shown in Figures 1 and 2, through the instrumentality of tiles or slabs, and

Figure 4 is a perspective view of the corner block per se.

With particular reference to the drawings, there is shown in Figure 1 a wall formed of block members, disposed one upon" the other in vertical alinement and separated from the next adjacent set of vertically alined blocks, through the instrumentality of front and rear tiles or slabs 6. The

wallfconstruction also includes the provision of corner blocks 7 also supported one upon the other. in ,vertical alinement, and connected to the first-mentioned blocks '5 also through the instrumentality of the slabs 0rtiles.

The main blocks 5 are of substantially rectangular configuration as shown in Figures'l and 2, and are hollow. The blocks 5 arefor'med upon-their front, and rear sides with projecting,fdoveatailed' heads 8 of a height equivalent tolth e height of the block; These dove 't'ailed heads 8 are further so formed as to have their opposite ends spaced inwardly of the adjacent ends of the block 5, as clearly shown in Figures 1 and 2. The grooves 8 at the ends of these heads 8 have their inner straight edges raised from the adjacent surface of the block for providing shoulders 9 upon opposite ends of the block for purposes hereinafter described.

It is to be understood that in the art of constructing a wall, these blocks 5 are laid one upon the other, and are secured together by mortar or the like holding means. It is further to be understood that the adjacent vertical rows of the block members 5 are to be secured in spaced relation with each other by the tiles or slabs 6 as above set forth. The ends of these tiles or slabs 6 are out upon a bevel 6' as per Figure 1 for fitting within the grooves 8' upon opposite ends of the heads 8 of the blocks 5 and are secured therein by the filling of mortar or the like between the shoulder portions 9 of the blocks, and the adjacent inner surfaces of each slab or tile 6.

The end blocks 7 are substantially squareshaped and are also hollow. The front and outer end walls 7 and 7 are each formed at one end with a vertical V groove 8" inwardly of the adjacent ends of the block for forming shoulders 9'. The inner corner of this block 7 is formed with a vertical mitre groove 9", the outer ends of which are also inwardly of the adjacent ends of the sides of the block for providing additional shoulders 9' and it is to be understood that the outer tiles or slabs 6 have their bevelled ends engaging within Vl-grooves 8" as shown in Figure 6, and that the bevelled ends of the inner tiles or slabs 6 have their bevelled surfaces contacting each other for forming a mitre joint within the mitre groove 9" of the block. As in the first instance, these tiles or slabs 6 are also secured to the corner block by mortar or the like between the shoulders: 9' andthe adj acentv inner surfaces of each of the tiles or slabs.

In view of the above description, it is believed by me that the advantages of a wall constructed with my improved, building block employed in conjunction with the tiles or slabs 6 will be readily appreciated by those skilled in the art, and while I have herein shown" anddescribedthe preferred embodiment of the present" invention,

it is nevertheless'to be understood that having the ends oifset inwardly from the ends of the bodyportion, the ends of saidprojections being formed. withrecesses having the inner faces offset from butparallel with the sides of the body portion and the outer walls inclined outwardly to the outer ends of said projections.

2: The combination-with spaced tiles havingtheopposite ends bevelled, of a building block having a rectangular body portion, a air of verticalsides .of said block having projectionsformed" thereon offset from the ends of said body portion in the line of'the;

wall into which theb-lock is arranged, said offset ends of the projection having grooves formed therein with the inner-portions paralleliand offset from the respective sides and the outer portions inclining outward to the: ends of 'the projections whereby the bevelled.

ends of the tiles will fitv in the grooves in said projections in wall forming relation.

In testimony whereof I afiix my signa-i ture; i

DORRELL n. BRIGGS.
